Hello,
i just noticed a strange problem with expunge_mode:delayed which i cannot explain. it's probably a
lack of understanding on my side since i'm no cyrus-imap expert not even an email expert :)
OK, let me explain my problem. recently i discovered that my spam mailbox had 14.000 messages in it,
which surprised me necause i thought, cyr_expire deletes messages every day. i checked the mailbox
with cyrdump and according to cyrdump it was empty. so i ran some tests to understand what went wrong:
this is the mailbox for the test:
localhost.localdomain> info user.me.Junk
{user.me.Junk}:
condstore: false
duplicatedeliver: false
expire: 7
lastpop:
lastupdate: 21-Nov-2010 01:10:29 +0100
partition: default
pop3newuidl: true
sharedseen: false
size: 0
squat: false
first test with expunge_mode:delayed
$ ls -l /var/spool/imap/user/me/Junk/
total 24
-rw------- 1 cyrus mail 4 Nov 21 00:51 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 00:51 cyrus.header
-rw------- 1 cyrus mail 96 Nov 21 00:51 cyrus.index
nothing in there. let's move a message in there:
$ ls -l /var/spool/imap/user/me/Junk/
total 32
-rw------- 2 cyrus mail 2952 Oct 25 2005 172936.
-rw------- 1 cyrus mail 836 Nov 21 00:58 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 00:51 cyrus.header
-rw------- 1 cyrus mail 184 Nov 21 00:58 cyrus.index
and delete the message. status after deletion:
$ ls -l /var/spool/imap/user/me/Junk/
total 32
-rw------- 3 cyrus mail 2952 Oct 25 2005 172936.
-rw------- 1 cyrus mail 836 Nov 21 00:58 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 00:51 cyrus.header
-rw------- 1 cyrus mail 184 Nov 21 01:01 cyrus.index
$ /usr/lib/cyrus-imapd/cyrdump user.me.Junk
<imapdump uniqueid="372a2ba243fb45a1">
<mailbox-url>imap://pyramid/user.me.Junk</mailbox-url>

<flag name="\Deleted" user="*">172936 </flag>
<flag name="\Draft" user="*"></flag>
<flag name="\Flagged" user="*"></flag>
</flags>
</imapdump>
still there but flagged as deleted, which is OK, cyr_expire should take care:
$ /usr/lib/cyrus-imapd/cyr_expire -v -E 90 -X 0
Expunging deleted messages in mailboxes older than 0 days
expiring messages in user.me.Junk older than 7 days
expiring messages in user.me.VIRUS older than 7 days
but it is still there:
$ ls -l /var/spool/imap/user/me/Junk/
total 40
-rw------- 3 cyrus mail 2952 Oct 25 2005 172936.
-rw------- 1 cyrus mail 836 Nov 21 00:58 cyrus.cache
-rw------- 1 cyrus mail 184 Nov 21 01:04 cyrus.expunge
-rw------- 1 cyrus mail 153 Nov 21 00:51 cyrus.header
-rw------- 1 cyrus mail 96 Nov 21 01:04 cyrus.index
but cyrus thinks it's really gone:
$ /usr/lib/cyrus-imapd/cyrdump user.me.Junk
<imapdump uniqueid="372a2ba243fb45a1">
<mailbox-url>imap://pyramid/user.me.Junk</mailbox-url>
<incremental-uid>0</incremental-uid>
<nextuid>172937</nextuid>
<uidlist></uidlist>
<flags>
<flag name="\Answered" user="*"></flag>
<flag name="\Deleted" user="*"></flag>
<flag name="\Draft" user="*"></flag>
<flag name="\Flagged" user="*"></flag>
</flags>
</imapdump>
no messages, not even deleted ones.
now with expunge_mode_immediate:
$ ls -l /var/spool/imap/user/me/Junk/
total 32
-rw------- 2 cyrus mail 2952 Oct 24 2005 172937.
-rw------- 1 cyrus mail 836 Nov 21 01:07 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 01:07 cyrus.header
-rw------- 1 cyrus mail 184 Nov 21 01:07 cyrus.index
delete message and check flags:
$ ls -l /var/spool/imap/user/me/Junk/
total 32
-rw------- 3 cyrus mail 2952 Oct 24 2005 172937.
-rw------- 1 cyrus mail 836 Nov 21 01:07 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 01:07 cyrus.header
-rw------- 1 cyrus mail 184 Nov 21 01:08 cyrus.index
$ /usr/lib/cyrus-imapd/cyrdump user.me.Junk
<imapdump uniqueid="372a2ba243fb45a1">

<flag name="\Deleted" user="*">172937 </flag>
<flag name="\Draft" user="*"></flag>
<flag name="\Flagged" user="*"></flag>
</flags>
</imapdump>
message still on disk but correctly flagged as deleted. after running cyr_expire:
$ ls -l /var/spool/imap/user/me/Junk/
total 24
-rw------- 1 cyrus mail 4 Nov 21 01:10 cyrus.cache
-rw------- 1 cyrus mail 153 Nov 21 01:07 cyrus.header
-rw------- 1 cyrus mail 96 Nov 21 01:10 cyrus.index
message was deleted.
it seems that with expunge_mode:delayed running cyr_expire does not delete the message files, why
and how can i change that? for now my workaround is to set expunge_mode:immediate.
if i miss something or my test is bogus, please let me know, i'm willing to learn :)
Thanks.
regards,
-ap
